Haven't seen anybody ask the most important question: will you be charging during the day or at night.
I thought I had read day time.
I mean, it's possible just stupid expensive.
The daytime components based on 100 miles/day average (~35kWh)
Is the truck that efficient? It doesn't exist yet, so anything we read is just some billionaire's hopes and dreams for it. I'd use 500 watts/mile just for al little more padding.
would be a minimum 5kW inverter (7-8 hour charge time), and I would guess about 10kW of PV (~25x 400W panels), just to support the car.
My math comes out different. Much higher larger.
Good clarification questions!
My average use: every other day or every few days, 100 to 200 mile round trip. I live in a remote area and have to drive a long ways to small towns. The Cybertruck would be a second vehicle and I would not be fully reliant on it.
Let's just average that and say you need to recover 150 miles per day?
150 miles at 500 watts per mile = 75 kWh
To get 75 kWh into the EV in the winter, I punched Phoenix into PV watts. It shows you'd need about a 22 kw array.
The problem is that their current "wall connector" maxes out at 11.5 kWh, so you'd need to store all the energy past what the car can take (22kw-11.5kw) for the hours the array is producing more than 22kW.
More math is required to get actual sizes.
12-15 kW inverter
22kw of solar charge controller
40+kWh battery bank
Smart EVSE, like an OpenEVSE or Emporia that can track solar output and adjust car charging.
Side question, you are already off grid, why make this a dedicated system? I'd just expand my current power system.
